WORCESTER, Mass. (AP) — Two people are held without bail after Worcester police they stole $400 in lottery winnings they saw a disabled woman collect at a convenience store.

The Telegram & Gazette reports that 26-year-old Sayed McKenzie and 38-year-old Wendy Laporte of Worcester pleaded not guilty Friday to charges of masked armed robbery and assault and battery on a disabled person.

Police said the pair followed the woman, who has cerebral palsy, after Laporte saw her cash the lottery ticket. Prosecutors said McKenzie, wearing a mask, approached the victim outside her apartment building, threw her to the ground and threatened to shoot her before stealing her money.

McKenzie’s lawyer said he denies the allegations.

Laporte is held until a dangerousness hearing Tuesday. The judge set McKenzie’s bail at $50,000 but revoked his bail in an unrelated assault case.
